Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the GV beats 4 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the GV.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 2017 (77.6% pass). Weakest: 2018 (68.3%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.

HYOSUNG GV FAQ

answers computed from the data above · terms in the glossary

Is the HYOSUNG GV reliable?

The HYOSUNG GV is about average for its class: 73.9% of its 1,192 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4406 of 5426 models.

What does a GV fail its MOT on most?

What is the best year of GV to buy used?

By first-time pass rate, 2017-registered examples do best (77.6%) and 2018 worst (68.3%). Condition and history still trump the year.

How many miles will a GV last?

The median GV shows 5,329 miles at test, and examples around 20k miles still pass 58.7% of the time — mileage alone rarely kills one.
